Abstract of the Disclosure A stabilized activated percompound bleaching composition com- prises a mechanical mixture of a bleaching percompound, such as sodium per- borate tetrahydrate, an activator for such percompound, such as Z-[bis(2- hydroxyethyl)amino]-4,6-dichloro-s-triazine, a molecular sieve zeolite, such as a anhydrous type 4A synthetic molecular sieve zeolite and a higher fatty acid, such as myristic acid. The bleaching composition is made by mechanical- ly mixing the various powdered constituents, preferably by tumbling at about room temperature, and the product resulting is more stable on storage and more effective as a bleach in removing various stains from laundry than are similar products which do not contain the higher fatty acid. Also within the invention is a stabilized activated percompound bleaching detergent composi- tion, including the described bleaching composition plus a synthetic organic detergent, such as sodium higher linear alkyl benzene sulfonate. The method of manufacture of such bleaching detergent compositions are also described.
